We performed a numerical simulation to investigate the electromangetic effect on the flow field around the blunt nose body. The main flow is created by the hypersonic shock tunnel HIEST and the applied magnetic field is created by the magnet inside the body. In the experiment, the shock layer enhancement around the body is clearly observed. On the other hand, the numerical simulation based on the typical thermochemical model could not reproduce the experimental result. To clarify the discrepancy between the numerical and experimental results, we investigated the effect of the thermochemical model on the flow field. Numerical results suggest that the electric conductivity inside the shock layer predicted by the typical thermochemical model is considered to be much lower than the value created by HIEST.
